"Okay, so my ak had stopped feeding .20 bbs properly so I had to shoot .12 bbs. Until I got these mags. They never skip a shot! I LOVE these magazines!!! It shoots .20 like a charm! And I hate how high cap mags you have to wind the knob, and they sometimes skip shots, but these bad boys have never failed me!!!! I recommend u get a speed loader for these mags for faster reloading! But honestly, BUY THESE. And the metal is VERY strong and they ad weight to my gun which make it feel even more realistic! U won't be disappointed!"
